Abstract
A RF sniffer module and method for detecting the availability of cellular communication channels for data transmission. The module monitors the channels used in a cellular communication network to determine when a particular channel is idle, meaning it is not being currently used for communication. The module communicates the status of the channel to an overlay system. Thus, the overlay system is informed that a particular channel is idle and thus can be used for data transmission or that the channel is not available and thus the overlay system can not use that channel without interfering with the operation of the cellular communication network.
